Enteligent developed the Enteligent ™ NMax Rapid Shutdown Device with Optimization by integrating and building upon the advanced microprocessors and PLC transceivers from Texas Instruments (TI), creating a truly smart system.
Two components have become particularly important to the design of the Enteligent NMax Rapid Shutdown Device with Optimization: TI’s microprocessors and power-line communications (PLC) transceivers.
TI’s C2000 microprocessor is crucial for managing the real-time response of Enteligent’s NMax devices. For instance, with the NMax RSD with Optimization, the microprocessor continuously monitors the PV module’s current and voltage output to determine whether to instantaneously engage the optimization circuitry to correct for shading or other causes of suboptimal solar generation. The C2000 also provides the processing horsepower to negotiate optimal PV string current to achieve maximum power production tracking (MPPT), all the while adjusting load response to diminish the inferior effects of the solar inverter’s MPPT schema. The microprocessor administers daily health condition monitoring routines to diagnose any internal malfunctions of this critical safety device. The microprocessors are also used in the Enteligent NMax Rapid Shutdown Transceiver to ensure asymmetric communications per channel and minimize crosstalk and false arc-fault issues plaguing other Rapid Shutdown systems. The microprocessor-based optimizers collect and transmit performance data for each panel, making Enteligent’s system truly smart.
Enteligent also utilizes PLC transceivers to send data over the power lines without requiring additional wires or complicated wireless networks. In addition to performing standard RSD communications to industry-standard SunSpec™ RSD Certified requirements, these transceivers transmit performance data for each panel collected at the rooftop to the ground-based transmitter, an intelligent and proprietary data transport standard developed by Enteligent. This panel-level insight allows installers and consumers to monitor and optimize panel performance to manage energy costs and reduce labor, time, and maintenance costs for needed repairs.
